Question 1

Which software development methodology emphasizes iterative cycles, team collaboration, and flexibility to adapt to changing requirements over following a rigid sequential plan?

Accepted Answer

Agile

Answer

Agile methodology organizes work into short iterative cycles (sprints) and prioritizes responding to change over strict upfront planning, making it well-suited for complex projects with evolving requirements.

Question 2

In object-oriented programming, what does 'encapsulation' mean?

Accepted Answer

Bundling data and the methods that operate on it into a single unit while restricting direct outside access

Answer

Encapsulation groups related data and behavior into a class and hides internal implementation details from the outside, protecting data integrity and reducing complexity.

Question 3

What is the primary purpose of a 'pull request' in a collaborative software development workflow?

Accepted Answer

To request that teammates review and approve code changes before merging them into the main branch

Answer

A pull request notifies team members that a developer has completed changes on a branch and is asking for peer review and approval before those changes are merged into the shared codebase.

Question 4

In web development, what is the primary distinction between front-end and back-end development?

Accepted Answer

Front-end focuses on what users see and interact with; back-end handles server logic and data processing

Answer

Front-end development builds the user interface and client-side experience (what you see in a browser), while back-end development manages server-side logic, databases, and the underlying functionality users don't directly observe.

Question 5

What is 'refactoring' in software development?

Accepted Answer

Restructuring existing code to improve its readability and maintainability without changing what it does

Answer

Refactoring improves the internal structure, clarity, and maintainability of code while preserving its existing external behavior — the goal is cleaner code, not new functionality.
